Shadow24v is on a distinguished road
I was looking around and Summit has a Pacesetter header AND cat-back for about $540 + S&H (i live in OH so i can just drive to the store and save on shipping ) only question is would i need a cat delete pipe or a replacement cat with this type of setup?

Good point on keeping it quiet. I don't want it to be ricer loud but i want it to make SOME noise when i give it a boot-full.

Biggest holdup ATM is time/money. Working a lot of OT at the moment and can't make it up to my g/fs parents to work on the 7 (and my DD has a to-do mod list as well lol)

I don't suppose anyone has any feedback on a ported 6-port N/A motor? What sort of changes does this give the motor? For example, with the planned ported 6-port with an S5 rotating assembly and intake, what could this motor rev to and still conceivably make power? 8 or 9?

Also, what rpm would stock style 2-piece apex seals withstand?
